I was checking switch cabling and thought — why am I doing this manually? I asked GitHub Copilot to do it. That question led down a rabbit hole of credential backends, hanging regex loops, and an AI that admitted it was being dumb.

I handed GitHub Copilot a /26 subnet and told it to plan IP addressing for a two-switch iBGP fabric with spine uplinks. Then we deployed it. Here's what happened.

What happens when you point an AI at two factory-fresh SONiC switches and say 'figure it out' — a real-world experiment in AI-assisted network discovery.

How EVPN with VRF isolation extends from the physical fabric to the Windows Hyper-V virtual switch — and why it's a real security upgrade over VLANs.

A practical, no-nonsense guide to Virtual Routing and Forwarding (VRF) for engineers who know networking but haven't clicked with VRFs yet.

BGP unnumbered already uses IPv6 under the hood. Adding IPv6 routes to your fabric is activating one address family — not redesigning your network.

How BGP unnumbered with loopback peering simplifies spine-leaf fabric operations at scale.

The origin story of nrecon-mcp — an open-source MCP server that lets GitHub Copilot SSH into network devices and explore them autonomously — designed entirely in a single Copilot conversation.

That moment when git reset --hard does nothing and files stay modified. A deep dive into solving the Git line ending mystery that haunts cross-platform teams.

A travel nightmare that started with a traffic cone on a hockey rink.
